Getting time out on initial subscription request

[PeterHiross]

Yes, we do have .NET Data Adapters. Looking in our Adapters.xml file I do not see any parameter <Param name="timeout"></Param>. Do I need to add it? What is the param's units? Milliseconds? What exactly does this parameter do? i.e., are there any side-effects?

What we have in our Adpaters's file
<data_provider name="xxx">
<adapter_class>com.lightstreamer.adapters.remote.R obustNetworkDataProvider</adapter_class>
<param_name="request_reply_port">xxx</param_name>
<param_name="notify_port">xxx</param_name>
<param_name="connection_recovery_timeout_millis">x xx</param_name>
<param_name="event_recovery">use_snapshot</param_name>
<param_name="name">xxx</param_name>

You can find the parameter listed, together with a short documentation, in the sample adapters.xml file of the StockListDemo Remote Adapter example in LS distribution package, in
DOCS-SDKs\sdk_adapter_dotnet\examples\Remote_StockListD emo_Adapters\Deployment\Deployment_LS\StockList_so ckets

So, you can add the line; the value is in milliseconds.
The timeout should only account for roundtrip delays in the Proxy Adapter / Remote Adapter communication;
in fact, we suggest that the Subscribe implementation should not be blocking.

The default timeout is 10000. A shorter timeout may cause more slow subscriptions to be refused. A very high timeout has a side effect on memory usage with a large number of subscriptions, which will be fixed only in the next release.
